PORTABLE P UUNCI-IIAINGQOR RIVETING MACHINE-p SPECIFICATION forming part of Letters Patent No. 761,528, dated May 31, 1904.

To aZZ w/tm it may concern:

Be it known that HENRY G. MoRSE,d eceased, late a citizen of the United States, residing in the city and county of Philadelphia and State of Pennsylvania, did invent certain new and useful Improvements in Portable Punching or Riveting Machines, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof. g

The invention relates to punching or riveting machines adapted to be supported and transported from above and of such a character as are especially adapted for use in operating upon bent angles, channels, Sac.

The object of the invention is especially to provide a simple and effective machine adapted to be used for punching or riveting and in which the upper tool is held. stationary and the lower tool moved to or from it to perform the work, this arrangement enabling the position of the tool to be nicely gaged with reference to the work and the work performed with the least possibletendency to error.

The nature of the improvements will be best understood as described in connection with the drawings, in which they are illustrated, and in which I Figure 1 isa front viewiof the tool equipped.

front elevation of this frame. (Shown in section on the line 9 9 of Fig. 8.) Fig. 10 is a side elevation of the frame, and Fig. 11 is a Sectional view on the line 11 11 of Fig; 8.

Aindicates the chain by which the machine is supported, the upper end of the chain being The chain is conupper end'B of a supporting-head B, which, as shown, has near its upper end a transverse erforation B mer in into a erforation B p b b of larger diameter, forming an interior chamber B*,.which communicates with a vertical port B having laterally-extending ports B B at its lower end. The head has also formed in it the port indicated atB said port open- }ing through the side of the head at both ends. :In an intermediate position on the head is formed the outwardly-extending annular shoulder, indicated at B, and the lower part of the head is cut away to form the shoulder B continuing below the ports B B in the form of a cylindrical extension B, from the bottom of which depends the threaded por-' tion B C is a pivot-pin fitting in the perforation B and having its outer end continued in the form of a curve and formed with a perforation therethrough, as indicated at C, the perforation openinginto the chamber B through ports D and D which make tight jointswith the shoulders B and B. As shown in Fig. 6, the lower portion of the sleeve (indicated at D is threaded and when in place has screwed into it the bearing and packing ring, (indicated at F,) the whole being held in place by'a nut F,

screwing on the threaded portion B of the head. A lateral extension of the sleeve has formed in it the ports D and D the first of which communicates with the lower lateral opening of the port B while the lower port D communicates with the port B. On the opposite side the sleeve has a bearing-thimble B, communicating through a port with the port D of the head, D indicating an annular bearing which screws into the end of the thimble D and through which passes the end of the tubular bail E, having the annular shoulder E at its inner end.

Gr is an exhaust-pipe connecting with the upper lateral opening of the port B H is a valve-casing having formed in it the cylindrical valve-chamber H, opening into a passage in the upper end of the casing, in which is secured the annular ring H having a central perforation H of the same diameter as the valve-chamber and,as shown, an upwardlyextending flange Hi having lateral ports H formed in it, which communicate through a port H with the port B in the sleeve D. Another port H formed in the valve-casing and opening through the walls of the cylindrical valve-chamber, communicates through the port B of the sleeve D, H indicating a third port formed in the valve-chamber and communicating with the bail I.

J is a piston-valve working in the cylindrical valve-chamber H and having, as shown, an annular portion J, which moves from one side to the other of the port H and above it a cylindrical portion J which moves partly in the cylindrical chamber H and partly in the cylindrical perforation H said cylinder J 2 having a downwardly-depending annular flange J 3 with lateral openings (indicated at J near its upper end. The valve is operated through a valve-lever K and pivotally supported on a link K, as shown in Figs. 1 and 5.

L is a supporting-frame having extending from one side of it the annular ring L, which is centrally divided, as indicated at Z, by a cut extending throughits base and nearly, but not quite, to its top, the base being provided with the perforated lugs L L through which passes a clamping-bolt M. (Indicated in Fig. 1.)

Extending in opposite directions from the frame L are the trunnions L L, the trunnion L having a central longitudinally-extending perforation (indicated at L opening laterally through ports L, the central perforation communicating with a lateral port L, which extends through a threaded projection L, L indicating a plug to close the end of the longitudinal perforation. The trunnion L is similarly provided with ports, the longitudinal port being indicated at Z the lateral ports at Z, and the longitudinal port ending in a chamber Z, from which extends a port L opening at the top of the ring L through a slightly-projecting annular extension, (indicated at L.) The bails E and I connect to common coupling-bases with annular bearings N, which lit on the trunnions L and L, and are provided with annular chambers (indicated at N which communicate through the ports L and Z" with the ports L i, N indicating a gland by which the packing in the chamber N is secured in place.

0 is a cylinder secured to the ring L of the frame L by a downwardly-extending annular flange O, O indicating the straight cylindrical part of the cylinder-chamber and O packing-rings secured in the downwardlyextending annular portion 0 by a gland O.

P indicates the top or head of the cylinder, from the center of which depends the downwardly-extending tool-holding device P; P indicating an outwardly-extending annular shoulder near the upper end of the device P, P a port or passage extending longitudinally from the top of the tool-holder P, and P a tube passing from side to side through the tool-holder P and having central ports P, which communicate with the port P. The lower end of the tool-holder, as shown, has an internally-threaded orifice P, into which screws the head P, to which the punch (indicated at P and having a central linger or point P") is connected by means of the coupling device indicated at P.

Q indicates a perforated head screwing into the top of the part P and coupled by a union Q, with a pipe Qf, which in turn communicates with the threaded projection L of the frame and through it with the ports L U L and tubular bail E.

R indicates the piston working in the cylinder O and having an upwardly-extending cylindrical extension R, which makes a workingfit with the annular shoulder P of the tool-holder P and forms a cylindrical chamber r between the outwardly-extending shoulder P of the tool-holder and the inwardlyextending shoulder R of the piston.

R is a sleeve extension depending from the bottom of the piston and working between the cylindrical tool-holder P and the packingrings held in place by the depending annular extension O of the cylinder.

S is a tool-holder for the lower tool or die, which is secured to the lower portion of the sleeve R", having, as shown, a split ring at its ends, terminating in flanges S S, which are clamped together by bolts S The toolholder is shaped to give convenient passage to the work below the punch 01' tool P and has a portion S adapted to hold and support the tool or die S beneath the upper tool.

R is a ring screwing .on the end of the sleeve R below the split ring of the toolholder S and provided with stripping-fingers R R, which when the piston R is in its lowest position extend below the punch P, as shown in Fig. 3.

T, Fig. 3, indicates a spring which, as shown,

has for its chief function the holding in proper I place of'the cupped leathers at the top and bottom of the cylindrical chamber r. To the extent of its strength it is obvious that the spring will also operate to push down the piston R and its connected parts, and this is menthe port 0 into the chamber B of the head B and through the ports B to the ports B and B The fluid constantly fills the thimble D and bail E, communicating from said bail through the ports L, L and L and the conduit Q and head Q, withthe longitudinal port P of the upper tool-holder, from said port passing through the lateral-ports P of'the tube I into said tube and through it into the cylindrical chamber r, where it acts on the lower shoulder R formed in the piston, pushing said piston and parts depending thereon, downward to their lowest position, or as shown in Fig. 3. From the other port B connected with the .port B pressure fluid passes to the port D, and thence to the port H of the valve casing H, and thence, the valve being in the position shown'in Fig. 5, the fluid passes up inside of the flange J of the cylindrical portion J and out through the lateral ports J into'the port H and thence, through the tubular bail I, to the ports'in the trunnion L, and thence throughthe port L to the cylinder 0, which is coupled therewith, as shown, by athimble 0, Fig. 2. The pressure fluid acting on the piston R raises it and its sleeve R the said sleeve carrying upward the tool holder S, and stripping-fingers R and brings the tools S and P into operation upon the plate, which, of course, is situated between them. When the work is effected, the valve J is moved upward, the portion J cutting off the supply of pressure fluid and the cylindrical portion J 2 moving-upward in the annular ring H until the lateral portsJ open on the upper side of said ring, when the fluid from the cylinder is free to flow backward through the bail I, port H ports J and ports H into the port H of the casing, whence it passes through the ports D and B to the exhaust-pipe G. The weight of the parts depending on the piston will of course tend to draw the piston down, the resistance of the work or from other sources being overcome by the constant fluid-pressure in the cylinder 9*, which thus acts as a pull-back cylinder.

The stripping-fingers R R press against the work asthe piston R and sleeve R move down and press it off the punch P Having now described the said invention,
